At a Glance
- Dominic Calvert-Lewin sees a early header ricochet off the upright.
- Aaronson fires the home side ahead with a well-placed effort in the second half.
- Matheus Cunha responds just three minutes afterwards.
- The Yorkshire side continue their longest Premier League unbeaten run since 2001.
Manchester United's disappointing recent struggles continued at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side not suffering even more disappointment against Leeds.
The Everton loanee headed a first-period effort against the woodwork for the confident home team before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had been held by struggling Wolves at Old Trafford earlier in the week.
However, against a team who had less time to prepare, Cunha levelled three minutes later when he latched onto a pass from substitute Joshua Zirkzee and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a mix of fitness issues and international duty.
Not that you would expect Leeds to care about that given their own tight schedule.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post in the dying moments.
The point extends Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers is having on Amorim's options.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that suffered poor results earlier in the season.
But without them, the boss has limited alternatives in attack.
He evidently does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
After memorable victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the hostile edge was not as evident as in previous fixtures.
The home fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that struck the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were struggling when a defensive error opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's position.
Instead, he is now masterminding significant improvement.
The task is not done yet but gradually, the team are getting nearer to securing their survival.
What Happens Next?
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
